Abstract
A bouncing-prevention mechanism for a breaker is characterized by comprising a side plate. A closing semi-shaft is hinged to the side plate and contacts a lever arranged on the side plate. A rotating shaft passes through a rotating shaft hole on the side plate, and a cantilever hinged with a swinging block is fixed on the rod body of the rotating shaft. A pivot pin is fixed on the swinging block, and a torsion spring is arranged on the cantilever. One end of the torsion spring presses against the outer cylindrical surface of the rotating shaft, and the other end presses against the outer cylindrical surface of the pivot pin. A limiting shaft is fixedly installed on the side plate under the swinging block and the cantilever and limits the rotation of the swinging block and the cantilever. Backstopping by swinging block and the limiting shaft, closing and unlocking effectively prevents rebounding during opening of the breaker, thereby enhancing the opening and closing performance of the breaker.
